1. What is Momentum?

Momentum is a fundamental concept in physics that describes the quantity of motion an object has. It is a vector quantity, meaning it has both magnitude and direction, and is calculated as the product of an object's mass and velocity.

2. How Does the Calculator Work?

The calculator uses the momentum formula:

Where:

• \( p \) — Momentum (kg·m/s)
• \( m \) — Mass (kg)
• \( v \) — Velocity (m/s)

Explanation: The momentum of an object is directly proportional to both its mass and velocity. Doubling either mass or velocity will double the momentum.

3. Importance of Momentum Calculation

Details: Momentum is a conserved quantity in isolated systems, making it crucial for analyzing collisions and other interactions. It's essential in understanding motion, force applications, and energy transformations in physics.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of momentum?
A: Momentum is measured in kilogram-meters per second (kg·m/s) in the SI system.

Q2: Is momentum a vector or scalar quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction.

Q3: How is momentum different from velocity?
A: Velocity describes how fast an object is moving and in what direction, while momentum incorporates both the object's mass and velocity.

Q4: What is the law of conservation of momentum?
A: In a closed system with no external forces, the total momentum before a collision equals the total momentum after the collision.

Q5: Can momentum be negative?
A: Yes, since momentum is a vector quantity, it can be negative when the direction of motion is opposite to the chosen positive direction.
